MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 436,288, dated September 9, 1890.

, Application filed May 26, 1890. Serial No. 353,251. (No infidel.)

To all whom it -rrury concern:

Be it known that I, GEORGE REID MELONEY, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certam Improvements in Milk-Coolers, of which the following is a specification. I

My invention relates to that class of apparatus in which water or other cooling-fluid is passed vertically through a sinuous or serpentine passage, the walls of which are formed of thin sheet metal, so that the fluid to b6 treated may be both cooled and aerated by allowing it to flow downward in a thin film over the outer surfaces of said walls.

. vThe invention consists in an improved manner of constructing and uniting the parts, whereby the cost of construction is reduced and increased strength secured.

In the accompanying drawings, Figure 1 represents a vertical cross-section through my apparatus. Fig. same. Fig. 3 is a side' elevation of one of the standards. Fig. 4 is a horizontal section on the line 4 4 of Figs. 1 and 2. 25, Referring to the drawings, A and B represent two horizontal top and bottom chambers, which are closed at the ends and communicate through a sinuous or serpentine passage 0, the walls of which are formed by two crimped or corrugated plates 0 c, of copper or other suitable sheet metal. These plates present an extended surface and are separated at their ends by intermediate vertical strips (1,

of rubber, lead, or other suitable packing material, which form the pentine passage.

At each end of the apparatus the two plates and their connecting-chambers are sustained by a standard E, composed, as shown in Fig. 3, of two'complementary parts e and e, adapted to fit one within the edge of the other, their inner or approximate edges being suitably curved to fit the corrugations of the respective plates, so that when the two parts are drawn together they will confine and compress the plates between them, causing the plates in turn to compress the intermediate packing in such manner as to produce a tight joint between the packing and the plates, and thus effectively 010 e the ends of the waterpassage. I prefer unite the two parts of 35 end walls of the sermilk or other- 2 is a side elevation of the tions, through which the upper chamber A throughout its 75 r the standard by through-bolts e as shown in the drawings; but theymay be united in anyother suitable manner.

The essence of my invent-ion in this regard lies in the employment of the corrugated plates in connection with the intermediate packing and a standard or frame adapted to. press the plates firmly against the packing throughout its length, and it is manifest that the details may be modified within the range of mechanical skill without departing from my invention.

The top chamber A is provided with a pipe or neck a, and the bottom chamber provided with a similar neck I) to permit the delivery of the cooling-fluid through the interior of the apparatus, either in an upward or in a downward directiom as preferred.

At the top of the apparatus I inount, p'ref- 7o erably on horizontal pivots F, a trough or vessel D to receive the milk, this trough being provided in the bottom-with fine perforathe milkv is delivered upon length, so that it may flow downward in thin films over the outer surfaces of the plates or walls 0 0, subject to the cooling or refrigerating influence of the internal fluid, and also subject to the action of theatmospherc. Arriving at the base of the apparatus thc fluid is received in a trough or chamber G,- provided with an outlet-opening g and with a strainer g.

In order that the milk may be the more thoroughly cooled and aerated, I propose to arrange on opposite sides of the apparatus adjacent to the sinuous plates flat vessels or chambers H lL-ada'pted to receive ice or cold water, so that the air passing freely between the inner walls of these vessels and the adjacent plates will bereduced in temperature and thus enabled to absorb the latent heat of the milk.

Having thus described my invention, what I claim is- 1. In a milk-cooler, the top and bottom chambers and the sinuous connecting-plates, in combination with the packing introduced between the said plates and the supportingmo standards, each consisting of the complementarv connected parts applied tothe plates and serving to bind the latter and the intermediate packing together transversely, substantially as described.

2. In a mi1k-o00ler, the standards, each consisting of two seetions having complementary sinuous edges and connecting-bolts, in combination with the intermediate sinuous plates, and the vertical pack lug-strips seated between the ends of the plates.

3. In a milk-cooler, the combination of the standards, the two sinuous plates forming a Water-passage, a trough to deliver the milk on the outer surface of said plates, and upright cooling-chambers arranged adjacent to the plates, substantially as described and shown. In testimony. whereof I hereunto set my hand, this 23d day of fifth month, 1890, in the presence of two attesting witnesses.
